WTB: Japanese Inert Ordnance

Japanese inert ordnance wanted - canon rounds, aircraft bomblets, grenades, mortars, mines, plus artillery and bomb fuses are all of interest.

Especially interested in any the following:
50mm Smoke Mortar
Type 99 Magnetic Turtle Mine
Type 97 Transitional Grenade
40mm HEAT Rifle Grenade
Aircraft Canon Ammunition

I’m based in New Zealand but have a great friend in Missouri who receives items from US based sellers which makes it easier.
